Road Operation and Maintenance Cost (VSS2000/463)
Overview
Background & policy context:
The research project is guided by the requirements of the basic cost-benefit-norm. The special norm will establish a cost structure with appropriate definitions, an object catalogue, technological and cost trends, requirements for input data, current/real unit cost, functional relationships, e.g. with traffic volume, asset age etc. Furthermore, a methodology will be described by which the benchmarks can be kept current. The infrastructure cost system will take into account different network elements and their operation and maintenance cost. Network effects by traffic which diverts from principal to secondary roads will also be taken into account.
Objectives:
The Swiss Association of Road and Transport Experts is preparing a basic norm for cost-benefit-analyses of road investment projects. An important element of those cost-benefit-analyses are changes in the operational maintenance cost of the infrastructure. The research project will develop a special norm to establish the respective cost factors and ways for their measurement. The study will complement the new SN 640 907 "Total cost of roads", where road operation and maintenance cost are not treated explicitly.
The first phase of the research project will deal with the cost of day-to-day road operations and maintenance. The intention is, in later phases of the project, to also develop cost benchmarks for road renewal cost as well as operation cost of road users.
Methodology:
For the essential facts of the operational cost road maintenance process or production models for standardized road sections, objects are defined. Based on the models are factory farms asked about the material and the energy demand according to the frequency of measures and according to the process-specific demand for labor and machine hours (roughly categorized). With appropriate cost rates can be determined the appropriate cost codes.
